Abstract: 1378853 Antifogging coating ESB Inc 3 Nov 1971 [4 Nov 1970 30 Sept 1971] 51159/71 Heading B2E [Also in Division G2]  Substrates on which water normally condenses from a moist atmosphere to cause fogging, are coated with a polyalkylene imine cross-linked with at least two polyfunctional compounds to provide a water-insoluble, hydrophilic anti-fogging coating. The functional compound contains at least two functional atoms or groups which may be ethylenic unsaturation, epoxy, epithio, carboxylic acid or anhydride, aldehyde, ketonic, isocyanato, isothiocyanato or phenolic hydroxy groups or halogen atoms. The polyalkylene imine may have pendant polar groups to promote adhesion to the substrate, and these may be formed by reaction of the polymer with a monofunctional compound having an unreactive polar group. The substrate may be a polymer or glass and may be a lens, mirror or window. In Examples, solutions of polyethylene imine, poly (2-methyl aziridine) and triethylene tetramine are partially reacted with various crosslinking materials including epichlorhydrin, N, N'-methylene bisacrylamide and glycidyl methacrylate, and coated on glass, polycarbonate, polymethyl methacrylate and an interpolymer of allyl diglycol carbonate, vinyl acetate and methyl methacrylate; the coatings are cured by heating; some of the polyalkylene imines also are reacted with monofunctional compounds including acrylonitrile, methyl methacrylate and styrene to form pendant polar groups.

Abstract: 1,150,184. Moulding sliding clasp fasteners. H. POREPP. 27 Nov., 1967 [14 Dec., 1966], No. 53950/67. Heading B5A. [Also in Division E2] Apparatus for forming a plastics thread into a continuous row of sliding clasp fastener link members comprises a toothed wheel 1, a thread guide 8 which moves axially across the circumference of the wheel and radially at one or both sides of the wheel and an anvil at one or both sides of the wheel level with the base of the teeth 2 in wheel 1. The wheel 1 is shown in cross-section in Figs. 5 and 6 and from above in Fig. 2, the formed fastener being also shown in this figure. The thread guide has a raised portion 9 around the outlet of the thread channel 8 and a finger 11 which fits between two teeth 2 on wheel 1. In operation the thread guide 8 moves from left to right laying a thread 3 between the teeth 2. The thread guide is lowered radially so that finger 11 is located between teeth 2 and the raised portion 9 stamps the thread against the anvil 4 forming a thickened portion 3c. At the same time, the finger 11 presses the thread against the raised portion 5 between the teeth and forms another dent in the thread. The thread guide is then moved radially and moved to the left to the position shown in Fig. 6, the flattened portion 3c forming the fastener member. The toothed wheel is advanced by one tooth and the process is repeated yielding a fastener of the type shown in Fig. 2. The thread 3 may be softened by heating during the process. In an alternative embodiment, the wheel 1 comprises two toothed sections with a space between them and an anvil is placed on both sides of the wheel, the resulting link member having the cross-section of a prone figure eight. The depression formed by raised portion 5 assists in fastening the fastener to a stringer.

Title: Acceleration detecting systems
Inventor: WHITCROFT JOHN ADAM
IPC: G01P15/16
Filed: 1968-04-26
Abstract: 1,267,362. Anti-skid brake systems. DUNLOP HOLDINGS Ltd. 25 April, 1969 [26 April, 1968; 3 Sept., 1968; 11 Oct., 1968], Nos. 19800/68, 32666/68 and 48189/68. Heading F2F. [Also in Divisions G1 and H3] In an antiskid brake control system, for measuring the angular acceleration or deceleration of a wheel, a first capacitor is charged to a first voltage proportional to the time interval between two consecutive pulses produced by a pick-up co-operating with a toothed wheel rotating with the body, a second capacitor is charged to a second voltage proportional to the time interval between the second of the two pulses and the next subsequent pulse, and a circuit responsive to said first and second voltages produces an output signal dependent on the angular acceleration or deceleration of said body. In Fig. 1, negative square wave pulses are produced at the collector of transistor TR1 by variation in the inductance of winding L due to the passage of the teeth of a mild steel toothed wheel through an air gap between pole-pieces (6, 7, Fig. 11, not shown). The leading edge of each pulse causes a bi-stable circuit to change state whereby capacitors C4 and C7 are alternately charged to voltages proportional to the time intervals between the leading edges of the pulses, each capacitor storing its charge while the other is being charged. Momentary conduction of transistors TR2 and TR5 discharges capacitors C4 and C7 at the start of their respective charging periods. The greater of the voltages on capacitors C4 and C7 is selected by diodes D3 and D6 for amplification by transistors TR6, TR7. Capacitor C9 and resistor R20 differentiate any increasing signal due to wheel deceleration, diode D10 shorting out any current flow through C9 due to acceleration. When the deceleration signal exceeds the threshold of a trigger circuit, a relay RL is energized to release the brake. Diode D9 provides speed compensation in order to make the system most sensitive to deceleration in a desired velocity range. In an alternative arrangement, Fig. 9, the voltages to which capacitors C3 and C4 are charged are applied to opposite ends of a potentiometer R13 so that when the voltage difference exceeds a predetermined value in the sense indicative of deceleration, transistor T5 conducts to trigger a monostable multivibrator to energize a relay RL to release the brake for the duration of the unstable state (adjustable by R17). Both capacitors C3 and C4 are simultaneously discharged through transistor T4 at the start of the charging period for capacitor C3. To allow for variation in wheel loading and/or coefficient of friction between the wheel and the road, resistor R17, Fig. 1, or R13, Fig. 9, may be automatically adjusted in accordance with the vehicle suspension displacement and/or vehicle body acceleration respectively. A capacitive pick-up may be used instead of the inductive pick-up.
